| 摘 要： | 对浙江长兴地区志留纪真盔甲鱼类的新材料进行了研究。形态学研究结果表明 ,雷曼煤山鱼 (Meishanaspislehmani)一属种成立 ,并非浙江中华盔甲鱼 (Sinogaleaspiszhejiangensis)的同物异名。在此基础上 ,运用分支系统学的原理 ,对真盔甲鱼目的系统发育关系进行了探讨 ,分析结果表明 ,中华盔甲鱼属现有的 3个种并未组成一个单系类群 ,而是一个并系类群。浙江中华盔甲鱼不能归到中华盔甲鱼属 ,建议另立一新属。

| Abstract: | The first work on vertebrates from the Silurian Maoshan Formation of Changxing, northwestern Zhejiang was done by Pan (1986a) who described the galeaspid fish Sinogaleaspis zhejiangensis, as well as fin-spines of Sinacanthus. From the same locality and horizon, Wang (1991) described another two galeaspid species, Meishanaspis lehmani and Changxingaspis gui. Since 1998, the authors have organized three subsequent excursions to Changxing, and collected abundant Silurian fish remains, which are suggestive of the Sinogaleaspis-Xiushuiaspis Fauna, the fish fauna originally described from Xiushui, Jianxi Province (Pan and Wang, 1980). The present account describes the eugaleaspid remains, with a revision of previously described material, and discusses the phylogeny of the Eugaleaspiformes. |
